Details how I installed AVIC-d1 in my 2004 Tahoe. Hope that helps, Arek
- first put the shifter all the way down to to 1st gear to get it out of the way. (turn the ignition key on to be able to shift).
- pull on the instrument/ dash bezel frame, you may start on the upper corner Rt. of the radio above the air vent. Dont use any tools just pul with your fingers it only snaps in place. Next pull above instrument cluster and all around. Wiggle it around the shifter and set aside.
- now you can see the (3) screws holding the radio. Unscrew and pull radio out.
- dont cut the existing connector instead order from Crutchfield.com GM Class II Data Bus Interface made by METRA model GMRC-01 (for non onstar and non Bose systems) If you have onstar and Bose there is another Metra interface box that supports it. This will keep your chimes and power to the radio for 15 minutes after you remove your ignition keys, just like with the factory radio. It also cames with GM 10 pin to 24 pin harness w/stripped leads. the wires are color coded and mach colors on avic unit. It also comes with insructions. You can olso contact Metra 1-800-221-0932 or www.metraonline.com. I paid for it at crutchfield around $79
You will need antenna adepter. GM plug is smaller. Get the GM antenna adapter from any auto parts store, few bucks. (the antenna pulls straight out off of your factory radio).
- make brackets for new avic matching the ones on the sides of the factory radio. I used Simson ties from home depot for the 2x6. I cut two pieces ou of one tie & drilled holes in one side to mount to side of avic and the other to match the existing holes in the dash. Just eyeball it to the same location like in factory radio. The black side brackets on avic will not be used, screw your brackets to the same holes after removing the black ones. You need to find bit longer screws the simson tie is thiker. Also avic is longer 3/8" so file or shave off some of that black plastic dash bracket on the back of the radio to push the avic all the way in. Done for the installation.
Now wirering: all according to instruction that came with Metra (power, speackers etc.)
The VSS (Vehicle Speed Sensor) GREEN / WHITE at the instrument cluster connector. Remove screws and pull the instr. cluster off. disconnect the connector on the back of it. Just pinch and pull. Look at the sides of that connector small letters on the sides on plastic. Look for side A wire pin 4. There is about three GREEN/ wites make shure is on side A of the connector not B. Pick yours from the list below
pin:
A1: Brown /White- MIL Control
A2: Not used
A3: BLACK/ White - Low Washer Fluid Control
A4: Dark GREEN/ Wite VSS wire
A5: White - Tach
A6: Gray - IPC Class 2 Serial Data.
- the brake wire tap to the one next to parking brake foot pedal, is only one Light Blue connected there.
-Wire for backup camera I just removed the tail light and tapped to the hot one at the light bulb when on reverse. Run the wire under the plastic trim on the right side floor, just snaps out. You can extend the wire if is too short.
That is it. Remember to press reset button on avic and drive for about 5-10 minutes for avics systems to initialise. After that the error msg. that your brake wire is not installed properly will not display anymore. Good luck. Arek
P.S I just installed XM tuner with NAV Trffic is working great
